Yellow evening primrose is a low-growing native perennial that opens its cheerful bright yellow flowers in the evening, attracting moths and other nocturnal pollinators. It thrives in well-drained soils in full sun to part shade and is quite adaptable to dry or rocky conditions once established. Minimal maintenance is needed — simply remove spent flower stalks to keep the plant tidy and encourage continued blooming.
